No it doesn’t.
>From what I know, Ontology deals with spacial related concepts upto
However there is need to take temporal or time related concepts into
consideration. So temporal ( time) inclusion makes it 4D.
In Enterprise architecture, When developing future (to be)
architecture of businesses and systems and organization, one has to take time
interval into consideration and the I have seen 4D concepts based on projections
For example, just taking years into consideration while developing
ontology for the same object - 2012 vs 2015 etc while projecting the
solutions. Further example: In 2012 - it may be Ontology for unman
space shuttle vs 2016 - 2 people navigated space shuttle !
Hope that clarifies the 4D concept!
MW: That is not at all what 4D means in an
A 3D ontology can take time into
account quite easily by stating the times at which some statement is true.
3D vs 4D is about the
fundamental nature of individuals and whether they are extended in time as well
as space. Under 3D they are extended in space only and pass through time, in 4D
they are extended in time as well as space. A consequence is that “me
today” is just an object in 4D, a state of me with a beginning at the
start of the day and an ending at the end of the day, where as in 3D I have to
say something like “me at all points in time during today”.
